Dorystoma

Dorystoma Harring & Myers, 1922

ref. ID; 1923

Manubrium forming a nearly circular plate with small handle projecting at posterior margin. With prominent supra-anal spine. Littoral species. (ref. ID; 1923)

ref. ID; 3245

Notommatid rotifers with short, stout, gibbous, illoricate body, with a distinct constriction between head and abdomen; the foot is very short and apparently two-jointed; the toes are short and decurved; at the base of the foot there is a short spine. The corona is oblique and consists of a marginal wreath of cilia with lateral, auricle-like tufts of cilia adapted to propulsion. The mastax is a specialized form of the virgate type; the trophi are modified as supports for the walls and a highly specialized epipharynx is present and serves to pierce the body wall of the prey by projection through the mouth. The eyespot is single and at the posterior end of ganglion. (ref. ID; 3245)
